The Rolex Deepsea D-Blue Dial is waterproof to an extreme depth of 3,900 metres (12,800 feet). Its 44 mm Oyster case is reinforced with the patented Ringlock System, which was designed to withstand water pressure equivalent to the weight of 3-tons on the crystal. Wearable and practical, the Oyster case and monobloc case middle are made in 904L stainless steel and the solid case back is made in G5 titanium.

The gradient D-blue dial is in two colours from brilliant blue to bottomless black. As a tribute to the partnership between Rolex and filmmaker-explorer James Cameron, the "DEEPSEA" marking on the D-blue dial is the same green colour as Cameron's submersible as perceived underwater. The markers and hands are treated with Chromalight luminescence with a distinctive blue glow that lasts up to eight hours with a uniform luminosity.

The unidirectional bezel is rotatable with 60-minute graduations in the Cerachrom (ceramic) bezel. The Cerachrom bezel numerals and graduations are coated in platinum. The screw-down crown features the Triplock triple waterproofness system. The domed sapphire crystal is 5mm thick.

The Deepsea D-Blue houses the COSC-certified manufacture Calibre 3135. The timepiece is fitted with a 904L stainless steel Oyster bracelet with flat three-piece solid links, an Oysterlock safety clasp and the patented Glidelock and Fliplock diving extension systems. Retail is $12,350, availability at boutiques & authorised retailers will be within two weeks from the time of this announcement.
